页面中用一个hidden标签:
<c:if test="${!empty user}">
当前用户:${user.userName}
<input type="hidden" id="useractor" name="useractor" value="${user.actor}"/>
</c:if>
然后在js中用这样获得:
alert($("#useractor").val());
目的是为了把用户的角色传过去,这样不同的用户可访问的内容不同,以控制它们的权限,其实完全没必要这么做,因为用户在登录成功之后,用户信息就已经保存在Session中,在各个页面之间是共享的,可以直接在页面上使用user,而无需其他地方传值.

看下面这段代码:
<tr>
<td colspan="4" bgcolor="#FFFFFF">
<div align="center">
<input type="button" value="修改" class="buttonC"
onclick="javascript:modifyUser('${contextPath }/userAction.do?method=toUpdateUser&userId=${user.userId }','actionDiv');"/>
</div>
</td>
</tr>
主要是这一句代码:
onclick="javascript:modifyUser('${contextPath }/userAction.do?method=toUpdateUser&userId=${user.userId }','actionDiv');"
是想让看一下${user.userId }的用法,直接往js里面传值。
现在看来有好多东西自己想都想不到,唉,还是要多经历!
